An object of my present invention is tov provide a frame construction,especially one for a window, having novel characteristics ofconstruction and which may be manufactured inexpensively,

A further object is to provide a stop on a frame which is limitedautomatically in its location, so that a minimum dimension may beestablished between the stop and another one between which a sash, forinstance, slides.

A further object is to provide a jamb with a liner strip which servesthe purpose of adapting the frame to dilierent kinds of wallconstructions and thicknesses and which so coacts with the janib that abead is formed tc serve as a limiting means for the position of a stop.

Still a further object is to provide a jamb and a liner strip with theiredges rabbeted together, such edges being of diiierent thicknesseswhereby to form a shoulder on the inner face of the jamb against which aport ion of a stop strip may engage for limiting lateral adjustment ofthe strip.

Still a further object is to provide a stop strip having a groove on itsface which engages a jamb, one side of the groove being adapted toengage a bead or other projection on the jamb and the groove beingentirely concealed when the stop strip is in applied position on thejamb.

Still a further object is to provide a bead and groove connectionbetween stop strips and side jambs and a rabbeted connection between astop strip and a head jamo, so that after the head and side jambs areassembled, the stop strips can be applied to the side jambe and the stopstrip can then be applied to the head janib.

With these and other objects in View my invention consists in theconstruction, arrangement and combination of the va-rious parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawing, in which: t

Figure l is a horizontal sectional View through the side jamb I" awindow, showing a liner strip applied thereto and the frame built into amasonry wall.

Figure 2 is a similar sectional view showing the frame in a brick veneerwall.

Figure 3 is a similar sectional View showing an eXtra thick masonry wallwith a subjalnb replacing the liner strip of Figures l and 2.

Figure 4 is a sectional view somewhat similar to Figure l, showinganother type of liner strip and showing a stop strip applied to thewindow jalnb.

Figure 5 is a sectional view through a head jamb of a window frame ofthe type shown in Figure 4, illustrating the liner strip and stop stripapplied thereto; and

Figure 6 is a perspective view of a portion of a side jamb, a linerstrip and a stop strip.

Referring to Figure 1, a side `iarnb ls indicated Serial No. 594,575

at lo. The inner edge of the side jamb 10 is rabbeted as indicated atl2. A liner strip A has a tongue 14 to engage the rabbet l2.

1t will be noted that the surface 16 of the liner strip A is shorterthan the surface 18 of the jamb 10. This provides a shoulder at 20. Inorder to make the shoulder 20 in vthe form of a bead 22, the janib 10 isdepressed at 24. Thus the top of the head 22 does not project beyond theinner surface of the jamb 10 so that the jamb can be more readilymachine formed and thinner lumber may be used to form it.

The liner strip A is provided with a groove 26 and a flange 28. Thegroove 26 is adapted to receive lath 3o and plaster 32 of a wallcovering of the wall in which the jamb 10 is mounted. The flange 28overlaps the lath or other covering 30.

It will be noted that the linervstrip A may be used with masonry, asshown in Figure 1, studding being shown at 34 and a urring strip at 36.The liner strip A may also be used in a brick Veneer wall, as shown inFigure 2. The brick veneer is shown at 38 and furring strips, insulationor the like 40 may be interposed between the studding 42 and the brickveneer so that the jamb 10 actually sets farther out with respect to thestudding than it does in Figure 1. In Figure 2, lath 44 projects intothe groove 26 of the liner strip A and the inner wall is faced withplaster 46.

As shown in'Figure 3, where extra thick walls, such as of masonry areused, a subjamb or jamb extension 48 may replace the liner strip A. Thesubjamb 48 has a tongue 14a and a surface 16a corresponding to thetongue 14 and surface 16 of the liner strip A. Thus the bead 22 projectsand forms a shoulder 20, the same as in Figures l and 2.

An inspection of Figure 4 makes it obvious that the shoulder 20 isadapted for limiting the adjustment ci an adjustable stop B toward awindow sash or toward the center of the jamb l0. The stop B has a groove52 wider than the bead 22 so as to permit adjustment of the stop striptoward or away from the sash 50, but its adjustment toward the sash ispositively limited by the bead. Adjustment is made possible by securingthe stop to the jamb l@ with screws 54 extending through enlargedopenings 56 of the stop strip B.

In Figure 4 and also Figure 5, a liner strip A is illustrated for anarrower wall, such as one of siding or shingle type. The strip A has atongue i417 and an edge 16o corresponding to these parts in Figure 1,but the strip is much narrower and the groove 26 is eliminated. Theflange 28, however, is retained and the tongue 14h is made narrow enoughto provide a groove, the sides of which are indicated at 58 and 60 andthe bottom at 62.

The side 58 is formed by the rear edge of the jamb l0. In Figure 5, Ihave illustrated a head jamb a with the liner strip A associatedtherewith. The head jamb, however, does not have a bead 22, but insteadhas a rabbet 64. A stop strip B (which may or maynot be grooved like thestrip B) engages the rabbet 64 to limit the adjustment of the stop striptoward the center of the jamb 10a, adjustment being retained by screws54a, through enlarged openings 56. The rabbet is used on the head jambbecause it simplifies machining and facilitates application of theliners. If a rib were formed on the head jamb it` would either have tobe cut off at its ends adjoining the side jambs or the top ends of theliners on the side jarnbs would have to be notched to fit over the rib.

The liner strip A or A provides additional nailing surface for the trim66 as well as providing for coaction of the inner wall covering with thejamb 10 (the liner strip being a portion of the jamb when securedthereto). It was found in practice that the mechanic or carpenter inapplying the stop strips B would set them too close to the sash with theresult that the sash would not slide easily. The shoulder 20 of the bead22 engaging one side of the groove 52 therefore predetermines the amountof channel clearance between the stop B and the center stop 68 (seeFigure 4) of the window frame so that the sash will slide easily at alltimes and in all positions of adjustment of the stop strips.

The groove 52 being wider than the bead 22, however, permits adjustmentof the stop away from the sash, if desired. The stop B having a groove52 rather than a projection of any kind makes it possible to easily sandthe stop strip at the factory.

Some changes may be made in the constructionV and arrangement of theparts of my device without departing from the real spirit and purpose ofmy invention, and it is my intention to cover by my claims, any modifiedforms of structure or use of mechanical equivalents, which may bereasonably included within their scope.

I claim as my invention:
